The ability to use existing steel infrastructure for carbon capture transportation and storage and (CCTS) networks is critical to their realization. As such there is a need to understand the corrosion performance of these materials under CCTS operating conditions. While the corrosion of steels in pure dry carbon dioxide is negligible the carbon dioxide stream in CCTS may contain significant levels of impurities. Therefore the effect of potential impurities on the corrosion of steels exposed to the carbon dioxide stream must be investigated. In the current work the effects of impurities such as water oxygen sulphur dioxide (SO2) and nitrogen oxides (NOx) on the corrosion of carbon and stainless steels under supercritical carbon dioxide conditions were investigated using a high pressure rotating cage. The corrosion of the steels was analyzed by mass loss and the morphology and composition of the corrosion products were analyzed using scanning electron microscopy (SEM) and electron dispersive spectroscopy (EDS).
